Hello! I have 2 Firewalla Golds in 2 locations using site to site VPN. Location 1 has GB fiber and the other location has 940/40. I'm unable to copy files between the 2 locations at more than 4MB at any time in either direction. Is there any thing I can look at?

  Upload or transfer from the 940/40 circuit will be limited to around 4 mega bytes per second. (slow upload)

  Download from the fiber will be limited by the fiber upload speed. 

  And both will be limited by the VPN you are using. Which is likely 120megabit/s.

  Agreed, but when downloading from the 1GB connection side, I'm averaging 2MB. That should be in the 100MB range, which it is not.

  And the fiber is 1GB symmetrical.

  "And both will be limited by the VPN you are using. Which is likely 120megabit/s."
  
  This a site to site Firewalla VPN tunnel, which is gigabit. Can you clarify this statement?

  That's the OpenVPN server speed limit on Gold:

  I think wireguard is now possible which should bump that to 500Mbps

  @Rich T. Thank you for your response. I'm still curious why I only get 2MB downloading from 1 GB network. 

  Do you happen to know of documentation on how to move the Firewalla devices over to WireGuard?

  It looks like it's in "early-access"

  In regard to the 2Mb download, did you run an internet speed test first? Id check that just prior to testing the site<->site just to make sure there's no an issue there.

  I'm experiencing basically the same thing.  ~500Mbit Speedtest.net on each end, but only ~20Mbit when tested throught the VPN.

  Site to site VPN is configured as Site A is the Server and Site B is the Client.

  If I am not connected to to the site to site VPN:
  Site A is Gold - 470Mbit to local ISP Speedtest
  Site B is Purple - 566Mbit to local ISP Speedtest

  If I test Site A, to Site B's local ISP, and vise versa, understandably it slows, to ~380Mbit.

  When I connect the site to site VPN, which is using Wireguard, and run the Speedtest from Site B to the Site A local ISP, I only get ~20Mbit.

  Download latency goes from ~72ms, no VPN, to ~195ms VPN connected.

  What is the speed of the internet site A and B (both upload download)? your fastest speed will be limited by the slowest

  That's it thanks.  Now a call to the ISP.

  From the Firewalla app.

  Site A - 464 Mb/s down, 23 Mb/s up

  Site B - 560 Mb/s down, 560 Mb/s up

  Your limit is site A, upload speed. 

  And in your case, if you do download teset from Site A to site B (pulling date out from B), then your speed should be limited by 464 mb/s
